LAM'P AND REFLECTOR FOR SAME.

SPECIFICATION forming partof Letters Patent No. 256,980, dated April 25,1882.

(No model.)

To all whom it may concern:

Be itknown that I, PATRICK H. (Borrow, a citizen of the United States ofAmerica, residing at Dallas, in the county of Dallas and State of Texas,have invented certain new and use.- ful Improvements in Lamps andReflectors for Same; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form apart of thisspecification.

Figure l is a perspective of my invention, part of the body of the lampbeing broken away; and Fig. 2 is acentral transverse section.

Like letters of reference refer to like parts in all the figures.

My invention has for its object the production of a lamp and reflectoradapted the one to the other, and in such points of construction asshall contribute to the efiectiveness of both, in that no part of theformer obstructs the rays of light reflected by the other, and bothshall be of simple and cheap construction; and my invention consists incertain devices and combinations of devices, hereinafter fully describedand specifically claimed.

A represents the body of the lamp; and it consists of the top and bottomplates, at a, of the form of an equilateral triangle having the cornersrounded, and the band c of uniform width, beaded at each edge, at a, andjoined at its ends in a seam, a at the center of one of the sides of thetriangle, which preferably constitutes the back of the lamp-body. Theseam being made, the edges of the triangular plates are sprunginto thebeading and soldered therein, as shown at a This manner of constructingthe joints of the body facilitates the soldering of the parts togetherin a satisfactory manner and results in a construction that protectssaid joints, as the edges of the band and not the joint bear the weight,abrasion, and wear occasioned when the lamp is set upon a table or othersupport and the exposed sides are seamless.

The body is provided at one corner of the top plate with a screw-cappedfilling-hole, B,

and at another corner with a screw-threaded collar, 0, adapted toreceive an ordinary burner, 0.

To adapt the lamp for suspension against aperpendicular surface, thereis applied a strap, D, secured by solder at the back and over the seama? in the band (4?, and extended upwardly a desired distance, and thenslanted down wardly and secured to the top plate a short distance backof the burner-collar O. The upright portion of strap D is perforated forthe reception of the nailor screw from which the lamp is to besuspended; and upon the slanting portion of the strap, at E, is securedby solder a. short piece of sheet metal, the edges of which are turnedto form flanges a, projecting inwardly and parallel with the body of thesame, which piece of metal I shall term, a grooved clip, and which isadapted to receive the tongue I soldered to the reflector G.

The object and advantage of constructing the clip E in this manner areto adapt it to be soldered to the strap without liability of the solderrunning into the clip, so as to impede the passage of the tonguetherein, as is commonly the occurrence when simply a loop of metal issoldered to the strap.

The reflector G is the frustum of a cone, the top of which is covered bya concave-convex disk, g, having a rin g or other suitable handle, 7L,soldered or otherwise attached thereto upon the outside. The bottom ofthe frustum is in a plane other than parallel to its top, and itsprofile may be in straight, curved, or combined straight and curvedlines, provided always that the lower side of the reflector shallterminate beneath the burner and in close proximity to the burner-collarO, as shown. The upper side of the reflector is perforated for the easypassage therethrough of the chimney D. By constructing the reflector ofthe shape show-11, supporting it upon a slanting strap, locating itslower side below the burner and closely thereto, and constructing thelamp-body in the form shown and locating the burner at one cornerthereof the maximum quantity of light is derived and reflected over thelargest possible area and the minimum of shadow produced by the lampitself is projected, while at the same time the reflector can be removedwithout removing the chimney, the chimney removed without removing thereflector, the lamp can be filled without removing either, andithas abroad base for contact with a wall when suspended, and its seams arefully protected from abrasion and wear.

To remove the reflector without removing the chimney, the tongue F isWithdrawn and the reflector lifted above the chimney, the opening in thetop of the reflector being sufficiently large to permit the withdrawalor partial withdrawal of the tongue with or without a slight tipping ofthe chimney, and the flexibility of the tongue permitting a slightcircular movement of the base of the reflector during its removal fromthe clip.

It is evident that by making the profile of the frustnm curved at thelower edges the reflector may be adapted to permit more or less light topass sidewise, as it is curved in outline, either inwardly oroutwardlyatsaid edges.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The lamp-body consisting of the triangular plates a a, the headedband a seamed at a and provided with the suspension andreflector-supporting strap D and at one corner with the filling-openingand at the corner op posite the seam a with the burner O, substantiallyas shown and described.

2. The strap D, provided with the clip E, having its edges turnedinward, in combination with the tongue F, secured to the reflector G,substantially as shown and described.

3. The combination of the reflector-supporting strap D, slanted asshown, With the reflector G, consisting of a frustum of a cone, thelower shorter side of which terminates be low and beneath the burner,and the upper longer side of which projects beyond the chimney and isperforated for the passage therethrough of the chimney, substantially asshown and described.

4. The reflector G, consisting of a frustum of a cone, the top of whichis closed by a concavo convex disk provided with a handle and with atongue, F, the upper side of which extends beyond and is perforated forthe passage of the chimney, the lower side of which extends andterminates beneath the burner, in

combination with a lamp-body provided with a slanted strap, D, having aclip, E, thereon, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
